Big SMTP Banner

While troubleshooting a mail problem with sending mail from my company to another organization, a coworker of mine found the strangest SMTP banner I’ve ever seen. The names have been changed to protect the RFC violators.

Needless to say, I think that the mail delivery problem we are experiencing will be due to the extra large banner.
